With the recent issues relating to shutting down Guzman, perhaps John can be a stop gap issue if the price is right. It's possible he may have enough in his tank left to come out of the pen in long relief or even spot starting.  I'm not sure that the Cards used his present skill set and capabilities well in the roles they placed him in, but I think he'd fit serviceably well in with the Cubs. What are your thoughts?
